There has been a significant amount of recent research in the computer networking community on the emerging wireless networking paradigm known as Mobile Networks; while the real-time image processing community have expended much effort on the development of scalable video encoding techniques and investigating the multipath streaming of real-time multimedia content. This work draws together the key elements of recent research in each of these areas and proposes a novel scheme for the multipath delivery of scalable video streams to users within multihomed mobile networks. We provide a hardware-based, multihomed mobile networks testbed and propose OPSSA, an optimised path selection and scheduling algorithm for use in multihomed mobile networks. Experimental results show our algorithm to outperform the representative algorithms when measured using the Peak Signal to Noise Ratio (PSNR) metric.
